SPRING BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 246,619, dated September 6, 1881. i Application nien october 2o, leso. (No modei.)

To all whom it may concern:

Beit known that I, MELVIN N. LovELL, a citizen of the United States, residing at Erie, in the county ofErie and State otPennsylvania, have invented certain new and useful Improvements in Spring Bed-Bottoms; and I do hereby declare the following to be a full, clear, and

' exact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the saine, reference being had to the accompanying drawings, and to letters or gures of reference marked there on, which form a part of this specification.

This invention relates to the construction of spring bed-bottoms which are so jointed that they may be rolled up and packed away in a small compass.

Heretofore in this class of bed-bottoms it has been common to place the slats upon short strips of sheet-iron connected together by the ordinary butthinge; but 4this form has been found defective for the reason that the hinge is weak and the sheet metal apt 'to break when a heavy body has been placed upon the bed, or when the device is rolled or handled. Anotherform of bed havingwedge-shaped blocks placed between the slats and hinged thereto has been in common use, but this device is palpably Weak, for the reason that the slats which are generally made of some light wood will not hold the screws of said hinges for any length of time, thus rendering the bed useless forthe purposes intended.

The object of my invention is to remedy these defects and produce a cross-stay that will be more strong and durable, and at the same time com bine lightness and cheapness, and to this end the nature of my invention consists in providing said cross-stays with clips havin pair of extensions formed on each end, and pintles for connecting each pair together, said pintles acting as bearing for the links, which connect the clips together, and constitute with said clips the cross-stays.

It further consists of parts and combination of parts which will hereinafter be described.

My device is illustrated in the accompanying drawings, as follows:

Figure lrepresents aplan view of a fragment of a bed-bottom having my improved construction, Fig. 2, an end view of the bed; Fig. 3, a like View, showing the bed collapsed or contracted; Fig. 4,21. view the same as Fig. 2, showing a slight variation; Fig. 5, a view ot the bed-bottom when rolled up, and Fig. 6, a view showing details ot' construction, which will more fully be explained hereinafter.

In the drawings, A A represent the longitudinal strips; B', the clips, which lie transversely to the strips A,and form, with thelinks B the cross-stay; C, the springs joined together by the links c.

The clips B' are provided with extensions e, arranged in pairs upon each end, and support a pintle, which may be formed with or attached to the extensions e in any suitable manner. The upper part of these extensions may have their inner faces made square-shouldered, so as to form with the top of the clip a socket for the slat to rest in.v By using this construction the strips can be held in place by a single screw or rivet, a, in such a manner thatit v will not turn laterally.

Link B may be made of one piece, or, if preferred, it may be madein two pieces and jointed at b. It is obvious, by so forming thc link, that there will be no departure from the main object of my invention. The object in jointing this link is to decrease the width of the bed-bottom, 4it' it be desired to use it upon a smaller-sized bed or a sofa-bedstead.

The clip may be made of any suitable metal; but I prefer to use malleable iron.

ThestripsA may be made of iron or wood, if desired, the clip being changed in size to suit the different widths.

To secure the bed when rolled, a hook, d, is provided on one end of the cross-stay, for the purpose of hookin g over thepivotpin b on the clip at the other end of the strip or stay.

1. In a spring bed-bottom, a series of clips forming part of the cross-stay, each clip having a pair of extensions at each end thereof, and pintles, substantially as described, to act as bearings for links, which connect the clips together, and constitute with saidv clips the cross-stay.

2. In a spring bed-bottom, a series of clips forming part of the cross-stay, each clip having extensions with square-shouldered inside faces, forming a socket for the longitudinal slat and pintles, for the purpose specied.

3. In a spring bed-bottom, a cross-stay hav- IOO ing clips provided with a pair of extensions at each end thereof, and pintles, substantially as described, in combination with links for connecting said clips together, in the manner set forth.

4. In a spring bed-bottom, a cross-stay having clips provided with a pair of extensions at each end thereof, and pintles, substantially as described, in combination with jointed links for connecting said clips together, in the manner set forth.

5. In a spring bed-bottom, a. clip,.B', having extensions e and pintles b, for the purpose specified.

6. In a spring-bed, a clip, B', having extensions e, provided with inner square-shouldered
